Forty years ago, Albert Hirschman emphasized that, in its decline, the theory of economic development had become fragmented into very different disciplines. At present, given the resurgence of both the problem and the theory of economic development, this fragmentation nourishes with very diverse elements (which are analyzed in depth) this theoretical resurgence. However, recovering a general conception of the problem without losing those specific contributions represents a significant intellectual challenge. The purpose of this paper is to review some of these topics, so as to contribute to the current path of economic thinking, which is revitalizing the concept of economic development.
